PYRONICS BZR-B BIAED AIR/GAS RATIO REGULATOR MODEL BZR-B-300

PYRONICS BZR-B BIAED AIR/GAS RATIO REGULATOR MODEL BZR-B-300

PRODUCT DESCRIPTION

Features & Benefits : BZR-B is designed with an adjustable compensation spring to bias the regulator providing a smooth transition to excess air operation at low fire. Using a gas adjuster downstream of a negative biased regulator, high fire can be set to stoichiometric conditions. As the system is turned down, the spring bias will subtract from the combustion air pressure causing the burner to go lean. Adjusting the screw under the cap assembly permits biasing the fuel/air ratio from high fire to low fire at a fixed, controlled rate.
